I have a wallstreet with a broken LCD. The caseing around the screen is in good condition so I don't want to pay the extra to replace that. on iFixit I saw that they sell the LCD panel by itself for around $30. unfortunatly they only have instructions for changing the display with the plastic casing still around it. is there anywhere else that would have directions to install this once I get it? also where can I get a working battery for this powerbook?
